What coding language to learn with tracking?

Hi, a different question perhaps, but im looking into learning to code to take my tracking to the next level.

What can people suggest to learn? is it Javascript only for tracking? Would be nice if its also “future proof” , alot is happening with Ai etc.

Also being able to pivot into a different industry one day like IT, if someday dont want to be in marketing no more.

Hope someone can help me in a direction :smiley:

I’m not a programmer, but as far as I’m aware, the JavaScript is the main language used by GTM. Tags, triggers, dataLayer - all of that is using JavaScript.

Yeah, think ill do the Odin project, as its free
